Batteries are a core technology for the transition from fuel-based to electric mobility. The power density of the currently available Li-ion batteries is much too low to enable the mobility range of cars with combustion engines. It is the purpose of this project to explore a new paradigm for battery construction, which promises to substantially lower the weight and enhance the storage capacity of Li-batteries. This project proposes to develop a strategy for the optimisation existing battery chemistries and take them to the physically possible limit in terms of storage capacity per volume and weight. Using a combination of sol-gel chemistry, polymer self-assembly and 3D printing, hierarchically structured (1mm -> 10 nm) battery electrodes will be created with the aim to determine the morphology that optimises Li-ion batteries in terms of the energy and power densities. The project consists of three tasks, (1) the development of sol-gel chemistries that can be co-assembled with block-copolymers to form lithium-metal-oxides for battery electrodes with well-defined 10-nm morphologies; (2) The development of a 3D plotting/ printing method to manufacture hierarchically structured materials that simultaneously optimise surface area for lithiation reactions and electrical and ionic conductivities across thick layers; (3) The translation of the optimised morphology developed in Task 2 to a scalable technology using the assembly of pre-manufactured 10-µm-sized building blocks.
